Traffic Generator
	Traffic Generators, TG2000 and TG1000 area unique test equipment for proactive and effective tests. Their patent-pending Capture and Replay ™ feature can be used to capture high speed real-time data such as VoIP or IPTV streams without affecting the quality. Captured files can be replayed at the same characteristics or at different speeds or to different destinations. Alternatively, they can be transferred over network for further analysis or for replaying at another location. Capture files are compatible with Ethereal and other pcap based analyzers. Traffic Generator also provides true gigabit wire speed (1.4 million pps per port) and controllable Traffic Injector ™. It can easily saturate gigabit Ethernet connections with traffic characterized by Ethernet, IP addresses, and TCP/UDP port numbers. Packet size and traffic rate can be specified in several ways. In addition, source and destination addresses, several other protocol fields and packet sizes can be incremented, decremented or randomized to create more realistic load effects. Traffic Generator can also be used for network measurements to measure latency, bandwidth, packet loss and other characteristics on multiple streams. The results are displayed in real-time in tabular format. Users can also save the results in CSV formatted files. Simena Traffic Generators are also capable of emulating BGP protocol by establishing neighbor connections to many BGP routers and sending all kinds of BGP messages. They can also be used for generating multiple stateful TCP connections. Traffic Generator comes in two models as TG2000 and TG1000 which are both multi-user, multi-port and portable appliance. It can be either mounted on a standard 19” rack or it can be used as a desktop traffic generator. It is completely managed by web GUI.

Traffic Capture and Replay ™

Traffic Generator captures high speed data packets and saves them for future analysis or for replaying them at different locations. Capturing can be selective by using packet filters and by number of packets.

Later, captured packets can be replayed as they are , or they can be modified including their payloads. In addition, they can be sent at the exact speed or at different packet or bit rates. Capture and Replay ™ feature preserves the quality of data packets even at high traffic speeds for accurate and effective tests of IPTV, Video on Demand, VoIP, and other real-time streaming technologies.

Capture Features

· Unlimited captures of data packets in real-time with extensive packet filters from layer-1 to 7.
· Captures packets inline while forwarding live traffic, eliminates the need for span ports or tap devices.
· Capture size can be specified by number of packets or file size.
· Captured packets can be saved in PCAP format for future analysis or replaying at different locations.
· Captured packets can be transferred over the network to another Traffic Generator.
· Captured packets can be analyzed by Ethereal or other PCAP based analyzers.

Replay Features

· Replays real-time data packets with extensive packet filters from layer-1 to 7.
· Replays packets as they are or modifies the content including the payload up to 10 bytes.
· Checksum fields are computed automatically on modified packets.
· Replays packets at the original speed or different speeds.
· Replays packets in fixed number of cycles or sends them continuously.
· Replays packets captured by PCAP based analyzers such as Ethereal.
· Network impairments such as packet loss, out-of-order packets can be introduced.

General Features

· Allows saving, loading, deleting and transferring capture files.
· Does not require a dedicated host or special GUI application.
· Easy to learn, configure and use via a web browser interface.
· Provides web based remote management including changing management IP address and password.
· Provides on-line hypertext user guide.
· Provides real-time throughput graphs.
· Provides real-time packet analysis with filters.

This feature is also available on Network Emulator NE3000 model.

Gigabit Wire Speed Traffic Injector ™

Traffic injection is another powerful feature of Traffic Generator. This feature allows users to generate very flexible Ethernet, VLAN, IP, IPV6, TCP, UDP and any custom protocol with custom payloads. To generate realistic traffic, address, port, any 2 byte data fields as well as packet size may be modified on every packet. Modifications can be done by means of incrementing, decrementing or randomizing. Every checksum field is recomputed for every packet by default.

The traffic amount can be specified by amount of packets, packet rate, bit rate, or time duration. Alternatively the traffic can be sent continuously at maximum speed. Up to 10 independent traffic streams can be generated per port.

Easy to use Web GUI makes traffic generation one-minute long task.

Features

· Gigabit wire speed packet injection per port, 1.48 million packets/second/port.
· Injects Ethernet, VLAN, IP, IPV6, UDP, TCP and many other protocol packets.
· Every Ethernet, VLAN, IP, IPV6, TCP and UDP protocol field can be specified.
· Easy to use Web interface dynamically changes for every protocol type.
· Payload for every protocol can be specified manually.
· Checksum fields are computed automatically.
· Dynamic packet streams can be generated by modifying, any address field or any two bytes.
· Packets can be modified by incrementing, decrementing and randomizing several protocol fields.
· High speed traffic injection in gigabit Ethernet.
· Injection rate can be specified in packets/second, bits/second or sending at maximum speed.
· Injection also can be specified by number of packets, time duration or in continuous mode.
· Up to 10 independent traffic streams can be generated per port.

Traffic Injection is also available on all Network Emulator models.

BGP Emulation

Simena Traffic Generators and high models of Network Emulators (NE3000 and PTC3000) are also capable of emulating BGP protocol by establishing neighbor connections to many BGP routers and sending all kinds of BGP messages. Following are some of the BGP Emulation features:

· GUI and CLI based BGP emulation.
· It can have multiple BGP neighbor connections.
· It can send OPEN, KEEPALIVE, NOTIFICATIONS and UPDATE messages with any custom content.
· All BGP protocol fields can be specified.
· Millions of route prefixes can be added, removed or flapped.
· Route flaps can be specified with "add to remove delay" and "remove to add delay" parameters.
· For multiple UPDATE messages inter update delay can be specified.
· BGP can be run at any TCP port.
· Both IBGP and EBGP are supported.

Stateful TCP Traffic Generation

Simena Traffic Generators and high models of Network Emulators (NE3000 and PTC3000) can also be used to generate stateful TCP connections to multiple destionations. Following are some of the TCP Traffic geneations features:

· GUI and CLI based stateful TCP connections.
· Multiple TCP connections can be made to multiple destinations.
· Multiple TCP connections can be made to a singe destination.
· Next hop router can be specified.
· TCP payload data can be specified.
· New payload data can be sent after the TCP connection is established.

RFC 2544 Network Performance Measurements

Simena's Traffic Generators also implement RFC 2544 network performance measurements. By generating packets with time stamps and sequence numbers users can measure latency, bandwidth, packet loss, amount of duplicate packets, and amount of out-of-order packets on multiple streams either in one direction or in both directions. Measurement results are displayed in a real-time tabular format. Users can also save the results in CSV formatted files.

Statistics

Traffic Generator has several statistics capabilities. It can show the packet send rate in packets and bits per second in tabular format. Similarly, it can display the throughput in graphical format. In addition, by means of the packet analysis tool, users can decode data packets in real time, optionally with packet filters.

Online Help

Although Traffic Generator is very easy to learn and use it provides an online user guide for complex emulations and administration tasks. Hypertext index lets the user navigate very easily. Convenient pop-up window can be used as a desktop reference.
